Abstract
Reaction of [Mo(NCMe)2(CO)2(CO)2(η5-C9H7)][BF4] with substituted cyclohexa-1,3-dienes affords the cations [Mo(1,3-diene)(CO)2(η5-C9H7)][BF4], which undergo regioselective reactions with nucleophiles and from which the diene can be readily displaced with carbon monoxide; with acyclic 1,3-dienes cis–trans isomerisaton of the 1-sunstituent is avoided by using the corresponding pentamethylcyclopentadienyl system allowing the stereoselective syntheesis of (E,E)-undeca-1,3,5-triene.Keywords
